Prevalence and determinants of non-communicable diseases in Saudi Arabia

Abstract

Abstract 
 Background
 Chronic diseases are considered the leading cause of mortality in Saudi Arabia. With a lack of national health surveillance systems, this study examines chronic disease prevalence and multimorbidity and their associated factors in Saudi Arabia.
 Methods
 Data was pooled from two cross-sectional national surveys conducted across the 13 regions of Saudi Arabia between March and July 2018. The study targeted Arabic speakers aged 18 years or older. The presence of chronic diseases was assessed according to self-reported medical diagnoses of chronic conditions. Multimorbidity was assessed based on the reported number of diseases (no condition, at least 1, and ≥ 2 conditions). Factors associated with chronic diseases’ presence were examined using regression analysis.
 Results 
 Out of the total participants (N= 7,317), the most reported chronic conditions were cardiovascular diseases (15.1%) followed by respiratory diseases (14.16%). The multimorbidity prevalence (≥ 2 chronic conditions) was nearly 5.6% (n= 564). Factors found to be significantly associated with the presence of chronic diseases were age, gender, employment status, marital status, and smoking. The findings showed that those who rated their health as fair or poor were almost three times more likely to be diagnosed with at least one chronic condition (95% CI: 2.21 - 3.56, P <0.001).
 Conclusions
 The study found a proportion of Saudis living with chronic diseases and multimorbidity with the highest risk among elderly people. The study findings are useful in building a sustainable health surveillance system and designing effective health policies and interventions to tackle the burden of chronic disease in Saudi Arabia.
